Martin MSP4100 SP Phosphor Bronze Light Acoustic Strings

Overview

Phosphor bronze winding wire does the tonal work in this Martin set, wrapped to the maker's specifications on each string. The set suits acoustic guitars and covers all six strings in a light gauge.

The reason to buy is a familiar bronze voice with clear trebles and deep basses from the maker of the set. The limitation is that the listing says nothing about a coating or a core material, so longevity is unstated.

Who it's for

Players with a steel-string acoustic who like a bright top and a full bottom end. Those who want extra-long string life from a coating should look at coated sets.

Pros and cons

Performance notes

The phosphor bronze alloy is said to give a bright, clear sound and a rounded low end. A light gauge takes less finger pressure than heavier sets but gives up some volume. Wound strings dull as oils and debris build up on the windings.
